When the monarchs find the sanctuary region, they are finding an area
that is 11,000 times smaller than the area the migration crosses. To
put this in perspective, we asked you to find something that is 11,000
times smaller than the area of a standard football field.

Here's one way to do the math:

A standard
football field measures 120 yds X 53.5 yds. First, we put the units into
feet, then found the area of the football field in feet:

Length
X Width = Area

Length:
120 yds X 3 ft/yd = 360 ft.

Width:
53.3 yds X 3 ft/yd = 159.9 ft.

360 ft
(Length) X 159.9 (Width) = 57,564 sq ft. (Area)

So, the
area of the football field is 57,564 sq ft.

Next, we
found the area of something that is 11,000 times smaller than the area
of a football field:

The area
of a football field (57,564 sq ft.) divided by 11,000 = 5.233 square
feet.

5.233 square
feet is about the size of a piece of poster board that measures 2.28 feet
X 2.28 feet on both sides.

Try This!

Place
an object that measures 2.28 feet X 2.28 feet on your school's football
field. Next, make a giant map of North America to scale. Add landmarks
such as your own home town, the Mississippi River, the Gulf of Mexico,
etc.

Pace
out the distance, in miles, from your home town to the monarch sanctuaries.
Put several landmarks you'd cross along the migration trail, to scale.
